Subject: [PATCH] Fix handling of text_message_outputs output structure in
 parallel translation example
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**Problem**:
The code assumed `ItemHelpers.text_message_outputs()` returned a single string per result (e.g., `"Hola mundo"`), but it actually returns a **list of strings** (e.g., `["Hola", "Mundo"]`). This caused a `TypeError` when joining outputs.

**Example of Failure**:
```python
outputs = [
    ["Hola", "Mundo"],  # From text_message_outputs
    ["Buenos días"],
    ["Cómo estás"],
]
translations = "\n\n".join(outputs)  # ❌ TypeError: can't join list to str
```

**Changes**:
- Wrap `text_message_outputs(...)` with `" ".join(...)` to safely flatten each agent’s output into a single string:
```python
  outputs = [
      " ".join(ItemHelpers.text_message_outputs(res_1.new_items)),
      " ".join(ItemHelpers.text_message_outputs(res_2.new_items)),
      " ".join(ItemHelpers.text_message_outputs(res_3.new_items)),
  ]
```

**Benefits**:
- Prevents `TypeError` by ensuring all outputs are strings.
- Maintains consistent formatting for the final joined output.
- Makes the example robust and easier to understand for users.

This change ensures the parallel translation workflow works reliably, even when agent outputs vary in structure.
